Description
Two memory-safety issues were identified in the Babelfish TDS protocol layer for Aurora PostgreSQL. CVE-2026-119923 involves the TDS connection-handshake handling and could allow a remote, unauthenticated actor to affect the database process. CVE-2026-119924 involves the TDS remote-procedure-call request handling and could allow a remote, authenticated actor to read adjacent process memory or cause a denial of service.
